[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a tire anti-slip device (hereinafter simply referred to as "slip device") which is wound around a tire and attached to the outer edge of the tire so that the side edge of the anti-slip device is attached to the tire side surface. The present invention relates to an outer tightening member that tightens toward a center to achieve close contact with a tire.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, a fastening member of this type has an outer surface formed to have a diameter smaller than that formed by outer edges 201 of a non-slip device 200 provided around a tire 100. A ring 300 and a smaller diameter than the outer ring 300,
A core ring 400 concentrically located at the center of the outer ring 300
And arms 500 radially extended from the outer surface of the core ring 400 to the inner surface of the outer ring 300. The wire diameters (thicknesses) are all the same. It was what had been formed.

[0003]

[Problem to be Solved by the Invention] However, an arbitrary portion 301 of the outer ring 300 corresponding to the connecting portion 700 of the both ends 202, 202 of the non-slip device 200 provided around the tire 100 has a centrifugal force when the connecting portion 700 is running. When pulled outward with
Since it is easy to bulge in the direction of the connecting portion 700 (outward), it is difficult to achieve sufficient adhesion of the non-slip device 200 to the tire 100, and there is a possibility that the anti-slip device 200 may be displaced. In particular, in the case of a so-called butting type anti-slip device 200 (illustrated example) in which both ends 202 and 202 are butted together and connected by a connecting metal member 800, the above-mentioned adverse effects are likely to occur.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a part of the outer ring or a part of the outer ring together with the center of the outer ring. An outer clamping member having a desired arm portion to be formed thicker than other portions and having a partially increased tensile strength is provided to prevent outward bulging caused by centrifugal force during traveling. Another object of the present invention is to eliminate slippage of a non-slip device wound around a tire.

[0005]

In order to achieve the above object, the technical measures made by the present invention include an outer ring and the outer ring.
Nuclear phosphorus smaller in diameter and located concentrically with the outer ring
Tire anti-slip device with multiple arms crossed over
In the tightening member of
Partly predetermined length corresponding to the connection part of both ends of the ear anti-slip device
Arc part of the whole tightening member more than other parts
This is to increase the tensile strength of the portion by forming it in a thick shape .

Further , the outer ring has a smaller diameter than the outer ring.
And multiple rings on the outer ring and the concentric core ring
Clamping member for tire anti-slip device with arms around
The tire slip on the circumference of the outer ring
Arc part of a predetermined length corresponding to the both ends connecting part of the tool
A desired arm of the arms from the arc toward the center

And

[0007]

According to the above technical means, the tensile strength of a part of the thick outer ring is increased, and the thick part of the outer ring corresponds to both ends connecting portions of the anti-slip device wound around the tire. When attached to the hook on the outer edge by locking, the thick portion of the outer ring is located below the connecting portion, and even if the connecting portion is pulled outward by centrifugal force during traveling, The thick portion of the outer ring located below the connecting portion is unlikely to bulge outward.

When a desired arm portion extending from the thick portion of the outer ring toward the center is formed in a thick shape together with a part of the thick outer ring, the thick portion of the outer ring may be formed. At the same time, the tensile strength of each of the thick arm portions is increased to prevent bulging.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

The outer fastening member A of the present invention is entirely formed of rubber or the like having elasticity, and is attached along the outer edge 4 of a desired tire anti-slip device C provided by being wound around the tire B. The outside of the stopper C (outer edge 4 ...) is attached to the tire B
The tire B is tightened toward the side center of the tire.
The fastening member A according to claim 1 in FIGS. 1 and 2 has a smaller diameter than the diameter formed by the outer edges 4 of the non-slip devices C provided around the tire B. An outer ring 1 formed; a core ring 2 having a smaller diameter than the outer ring 1 and located concentrically at the center of the outer ring 1; and a radial ring from an outer surface of the core ring 2 toward an inner surface of the outer ring 1. And a plurality of arms 3 which are bridged at equal intervals. The illustrated example is merely an example and is not limited. For example, the ratio of the diameter of the outer ring 1 to the core ring 2 or the number of the arms 3 can be arbitrarily set.

The outer ring 1 has a part of its circumference, for example, a circumferential part 1 extending between the arms 3a and 3b as shown in the figure.
a alone, the other circumferential portion 1b and the core ring 2, the arm 3 ...
The circumferential portion 1a is formed in a thicker shape (thicker wire diameter)
(Thick portion), and the circumferential portion 1b other than the thick portion 1a has substantially the same diameter as the core ring 2, the arm 3, and so on. Further, although not shown in the present embodiment, the outer ring 1 may be formed so as to have a thick portion along with a circumferential portion opposite to the thick portion 1a.

The anti-slip device C shown in the figure is a conventionally known net-type anti-slip device.
Are provided with locking hooks 5. However, this is merely an example, and other net shapes may be used.
Although not shown, a so-called ladder-type anti-slip device may be used.

Here, the method of mounting the tightening member A will be described. First, the non-slip device C is wound around the outer periphery of the tire B, and the end faces c and c 'of the anti-slip device C are connected by abutting each other. 4 are positioned on the side surfaces of the tire B, and the outer ring 1 of the tightening member A is extended and locked to a desired extent along the locking hooks 5 provided on the outer edges 4. At this time, the circumferential portion (thick portion) 1a formed into a thick shape of the outer ring 1 to increase the tensile strength is
The anti-slip device C is attached by being locked to the locking hooks 5a, 5b of the outer edges 4a, 4b corresponding to the connecting portion D of both ends c, c 'of the slip stopper C, and the thick portion 1a is positioned below the connecting portion D. Therefore, when the connecting portion D is pulled outward by the centrifugal force during traveling, the thick portion 1a of the outer ring 1 located below the connecting portion D is unlikely to expand outward and sufficiently resists the pull. Will be done.

Next, FIG. 3 shows a thick portion 1 of the outer ring 1.

a and the thick arm 3c further increase the force against the outward pull of the connecting portion D caused by the centrifugal force during traveling. In the illustrated example, the thick portion of the outer ring 1 is used. Although the thickness of the arm 1a and the arm 3c is substantially the same (the same wire diameter), the thickness is not limited to this and can be changed as appropriate.

In other configurations and mounting methods, etc.
Since it is the same as the fastening member A of the first aspect, the same portions are denoted by the same reference numerals, and description thereof will be omitted. In the same manner as in the case of the outer ring 1, even in the arm portion 3, although not shown, the arm portion facing the arm portion 3c may also be formed in a thick shape together.

FIGS. 4 and 5 show an embodiment of the present invention .
Although it is not shown, it shows an example of a fastening member A 'of another shape, in which the core ring 2 like the fastening member A shown in FIGS. 1 to 3 is eliminated, and between the adjacent arm portions 3a, 3c... And the like are formed so as to be directed toward the center, and have a substantially trapezoidal planar shape formed by connecting their lower ends to each other.
This is a type in which a desired fastening jig (not shown) is hooked on the above-mentioned hooks 6..., And the hooks 6 are pulled toward the center and tightened. In this example , one of the fastening members A ′ is used. The circumferential portion 1a of the outer ring 1 hanging on the hook 6a of
Are formed thicker than the other circumferential portions 1b and the other hooking portions 6b (FIG. 4), or the entire one hooking portion 6a including the circumferential portion 1a is used as the other hooking portion 6b. , And a thicker portion (FIG. 5) than the circumferential portion 1b to increase the tensile strength, and has the same effect as the fastening member A described above. still,
The other components, operations, and the like described for the fastening member A can be appropriately changed even in the present embodiment . The shape and the like of the hooking portion 6 are not limited to those described above. For example, although not shown, a flat triangular shape, a tip with a hooking hole for fastening a fastening jig, or the hooking hole is used. Is arbitrary such as a wide elliptical shape.
